Insulating materials

Abstract

Insulating materials which reduce heat loss are provided. The insulating materials include an air layer forming portion which forms a plurality of air layers, a lower cover portion which covers a lower side of the air layer forming portion, and an upper cover portion which covers an upper side of the air layer forming portion.

         7 . The insulating materials of  claim 6 , wherein the 1-3 surface and the 2-3 surface form a first apex,
 wherein the 3-1 surface and the 4-1 surface form a second apex, and   wherein the second apex is spaced apart from the first apex in a lateral direction so as to increase durability against an external force applied in the longitudinal direction.   
     
     
         8 . The insulating materials of  claim 7 , wherein the 1-2 surface and the 1-3 surface form a third apex, and
 wherein the second apex is formed between the first apex and the third apex in a lateral direction.   
     
     
         9 . The insulating materials of  claim 8 , wherein the first air layer forming portion comprises a 5-1 surface, a 5-2 surface which is bent and extends from the 5-1 surface, and a 5-3 surface which is bent and extends from the 5-2 surface so as to form a third air layer which is one of the plurality of air layers and is spaced apart from the second air layer,
